When I was a teenager, many of the young guys were taught it was a bad thing to be naked with one another or an older adult male. I had an older uncle, who had no shame about nudity and did help me to overcome my shyness while in college, as to nudity. No he wasn't being an adult pervert, but a an educated and wise mentor to me. There were times at our men's health and swim club when I was of collage age, he was like a father to me, especially in the locker rooms before changing out of our wet swimsuits. I would feel embarrassed and shy bearing it all around other men young or old. I always wore my favorite extra snug speedo swim briefs, but usually changing at home. After some encouragement and me loosing my feeling of shame, he would slowly and gently peel the tight wet clinging speedo down, then freeing my erect penis and behind from the still clinging wet material. Soon he had it down and off and the feeling was beautiful once my squirming young body was naked and showing it all. He made me feel really good and not ashamed being nude like the other naked men in the showers. It took some time, eventually overcoming my shyness and shame being naked around other men while changing in the gym and swim club locker rooms. It was my beloved uncle who really helped me and I'll always cherish his kindness and friendship.
